CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 225,219, dated March 9,1880. Application filed November 26, 1879.

To all whom it may concern:

Be it known that I, THOMAS HAYNES, of Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Car-Axle Lubricators and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specification, and in which- Figure 1 is a longitudinal section, partly in side view, of my improved car-axle box and shaft lubricator. Fig. 2 is an elevation of the inner end of the same. Fig. 3 is a vertical transverse section thereof, taken partly through the packing-ringyoke and axle, and showing the take'up mechanism of the packing-ring and dust-plate. Fig. etis a detail side view of the packing-ring and dust-plate and its take-up mechanism. Figs. 5 and 6 are detail perspective views of the dust-plate and the inner fixed part of the packing-ring. Fig. 7 is a perspective view of the brass. Fig.8 is a similar view of the brass-cap. Fig. 9 is an inverted View of the brass, and Fig. 10 is a vertical transverse section through the brass and one of its soft-metal plates.

Corresponding parts in the several figures are denoted by like letters.

This invention contemplates improvements in axle-boxes and lubricators, specially designed for car axles or shafts, though applicable for lubricating all classes of shafts or axles, and has for its object to take up wear of the dust-plate, to avoid the jamming of the brass, to distribute wear upon the axle or shaft and the wheels, and to provide increased bearingsurface with lightness of structure, and for the better distribution of the lubricant.

The nature of this invention consists of takeup mechanism for the packing-ringand dustplate, of a flange or collar upon the inner end of the box or lubricator, of the peculiar construction of this flange or collar, of the brass with diverging channels or passages leading from acommon passage or opening or cavity to and down each side of the brass, and of obliquely'arranged soft-metal plates or blocks inserted in the brass, substantially as hereinafter more fully set forth.

A in the accompanying drawings marks a car axle or shaft box, having the axle or shaft 13, and with its inner end provided, at the lower side, with a box or chamber, a, which is adapted to receive the lower end of the packing-ring presently described.

C is the-brass, which is fitted with a cap, C, and which is adapted to fit and rest upon the axle a.

Cleats or projections on the inside of the box A hold the brass in a horizontal position upon the axle or shaft.

The cap Cis provided with a lip, c, inclined inwardly and communicating with a hole in the cap.

In practice a beveled disk with an overhang ing scraper is a-ffixed to the outer end of the axle or shaft, which takes up the lubricant from the lubricant-reservoir in the box A and passes it to the lip 0 of the cap C". It then passes through the hole in the cap upon the brass.

The brass, in addition to having a broad elevation or reduced portion upon its upper sur face, over which fits and which holds the cap C in place thereon, is provided with a longitudinal concavity, (1, leading to an oblique hole or cavity, d, extending through the brass, and by means of which the lubricant is conducted to the axle.

e e are two lubricant passages or channels, leading or diverging from the hole 61, and extendingdown the sides of the brass, to further distribute the lubricant upon the axle.

In the brass C are inserted softer meta-l plates or blocks E, fitting in oblique holes or slots f f therein. These plates or blocks are designed, with their holes, to intercept the transmission of frictional heat and to lessen frictional contact and consequent wear between the brass and axle.

The obliquity of the holes and the arrangement of the plates orblocks distribute the'reduced wear between the brass and axle.

The blocks or plates E are of a wedge shape or tapering, as seen in Fig. 10, and dropped into their correspondingly-shaped holes with their smaller ends downward and with the under side of the brass turned upward. Af-

to connect the dust-plate to the axle.

ter this the smaller ends of the blocks E are hammered so as to flare them outwardly against the upper edges of their holes, when they will be secured therein, as also seen in Fig. 10.

F is the bottom part of the dust-plate, of a U-shaped form, and fitted upon the axle outside of the inner end of the lubricator and against the lu'bricator-box A, as seen in Fig. 1, to exclude the entrance of dust. The upper ends or legs of the dust-plate, which are bent at right angles, as seen in Fig. 4, are connected by headed screw-bolts g to the upper part of the packing-ring F and the lower part of the packing-ring F fitted against the under side of the axle or shaft and inserted in the box or chamber a, as seen in Figs. 1 and 6. The yoke F spans the space between the legs of the dust-plate F, and fits or rides upon the axle, thus serving, with the semicircular plate F The right-angled ends of the legs of the dust-plate rest upon springs h h, encircling the bolts 9 g, passing through said ends of the packing ring F.

It will be observed that the wear between the dust-plate and the packing-ring and the axle will be automatically taken up by the upwardly-pressin g springs h hon the bolts g, and thus obviate any possible entrance of dust into the lubricator that would be taken up and passed to the axle.

The yoke or packing-ring is cast hollow or in two parts, and the underneath semicircular plate with lateral extensions, and the former with a broad bearing-surface resting on the shaft or axle, while the latter may be fitted with and have fastened to it a correspondingly-shaped piece of wood, i.

The object of the aforesaid construction is to obtain broad bearing-surfaces between said parts and axle with lightness combined.

G is aplate, with downwardly-extending arms j, whose inner sides are provided with shoulders to rest upon meeting shoulders on the edges of the inner end of the lubricatorbox, while the outside edges of the plate G are provided with bolt-holes, through which the said plate is bolted to the box, and its upper edge or end with a cap or flange, G, fitting over the upper edge of the box, making a dust or water tight fitting cap. The side of this cap-plate Gr next to the wheel His provided with an archshaped or semicircular col lar or flange, G The collar or flange G which is cast around the opening in the plate G through which the wheel-axle passes, and between the box and the-hub or boss of the wheel, is curved, with its ends beginning or disposed almost at a point on line with the side edges of the said opening, and thence gradually curved outward, and being at its upper central portion farthest from said opening. The primary object of this collar or flange is to prevent the wheel, with its more or less wabbling motion, causing its axle-shoulder,

against which one edge of the brass rests or abuts, to jam the brass and risk the breaking of the same.

The divergence of the curve of the collar or flange is to distribute the wear over the wheel. Having thus described my invention, I claim and-desire to secure by Letters .Patent 1. The yoke F, cast hollow to give greater bearing-surface to the axle, combined with the packing-ring F and adjustable take-up bolt 9, as and for the purposes specified.

2. The yoke F, cast hollow to give maximum of axle-bearing to minimum of weight and material, and perforated to allow of lubrication, combined with the packing part F dust-plate F, bolt g, and spring h, as specified, for the purpose set forth.

3. The spring h, combined with the packingring F dust-plate F, and take-up bolt 9, said spring serving to hold both ring F and (lustplaie F in constant contact with the axle, as set forth, for purposes specified.

4. The removable cap-plate Gr, having collar G adapted to be secured to the box A and reduce the friction on the brass by abutting against the hub H, as and for the purposes set forth.

5. The cap-plate G, having collar G eccentrically arranged so as to distribute the friction along the area of the end of the hub and. relieve the brass thereby, as herein specified.

6. The brass 0, having an oil-passage, d, extending through to the axle, diverging passages 6, to carry away the overflow of lubricant, and hammered oblique soft-metal plates, as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of November, 1879.

THOMAS HAYNES.
